SPECIFICATION'forming part of Letters Patent No. 657,547, dated September 11, 1900.

Application iled May 21, 1900.

T0 all whom it may concern:

Be it known that I, J AooB WILLIAM KAMM, a citizen of the United States, residing at At.- wood, in the county of Douglas and State of Illinois, have invented a new and useful Unloading Apparatus, of which' the following is a specification.

This invention relates to unloading apparatus, and is particularly adapted for the unloading of corn or other grain from a wagon to a crib or granary, although it will be understood from the following description that the principles involved may be employed in apparatus for other purposes.

The object of the invention is to provide a simple and cheap construction which will be eflicient in its operation and will be particularly adapted for conveying corn from'a wagon to a crib and in dumping the corn into `the crib through the usual' side door thereof; also, to provide means forraising and lowering the bucket and manipulating the bucket in the dumping operation. 4

Further objects and advantages of the invention will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is anelevation showing the complete unloading apparatus and illustrat- Ing the position thereof with` respect to a wagon and a crib, from the former to the latter of which the corn is unloaded. Fig. 2 is a plan view of the carrier or traveler with which the bucket is engaged. Fig. 3 is a central longitudinal section of the traveler and showing the latch mechanism thereof in elevationand engaged with the bucket-supporting pulley. Fig. 4 is a transverse section of the traveler with the bucket-supporting pulley engaged therewith. Fig. 5 isa transverse section of the bucket and illustrating the means for latching the movable side in its closed position. V

Referring nowto the drawings, the unloading apparatus comprises, essentially, atrack 10, upon which the traveler operates, this track being in the form of a cross-sectionally rectangular rail. This rail has a series of hangers l1 in the form of bolts which are passed upwardly through the rail and have Seria1No.17,503. (No model.)

`secured to one of the rafters of the crib, it being understood that this apparatus is designed particularly for use in unloading corn into a crib.

In practice anumberof buckets are placed upon a wagon-hed from which the sides have been removed or upon a platform placed upon the holsters of a wagon, and the corn is shucked directlyinto the buckets,from which it is to be discharged into the crib, the buckets being necessarily raised from the wagon and discharged' into the top of the crib. During the hoisting and dumping operation the bucket is suspended from a traveler (shown in Figs. 2 and 3) which is slotted longitudinally to form two parallel legs 2O and 21 a-t its upper side, and upon the upper ends of these legs are I'ixed plates 22 and 23, respectively, having slots 24 and 25, in which are journaled supporting- wheels 26 and 27, adapted to restupon the upper surface of the rail 10 and support .the traveler. The separation of the legs20 and 21 is such as to permit free movement of the traveler along the rail and yet to prevent lateral displacement of the traveler, it being understood that, as shown in dotted Vlines in Fig. 4, the rail 10 lies below the plates 22 and 23 and between the legs 20 and 21. The slot of the traveler is continued through the bottom thereof, and between its sides and adjacent thebottom there is pivoted a latch 24', comprising an arc-shaped upper portion having a laterally-extending foot 25 at its lower end, this foot being adapted to lie in a horizontal position when operative. In the upper end of the arc-shaped portion of the latch there is formed a recess 27 and a shoulder 28 therebelow, and this recess and shoulder are designed for engagement by the si mi lar shoulder and recess 29 and 30 upon the end of a keeper 31, which is in the form of a rod pivotally mounted in the traveler. The notched o r recessed end of the latch is adaptedto normally lie forwardly, as shown in dotted lines in Fig. 3, and with thefoot ofthe latch retracted and in a slanting position; but when engaged by the keeper it is held raised and with the foot in a horizontal position, as

shown in full lines in Fig. 3.

be tilted, by reason of the pivotal connections of the rods 45 with the bucket, so as to dischargeitscontentsintothecrib. Afterdnmping the bucket is closed, and the latch-keeper is operated to cause the latch to release the link and permit the bucket to descend to theV wagon. The link is then disengaged from the bucket, and the traveler is moved to assulne a position over the next bucket, the link being connected With this next bucket, and it is raised and discharged in the same manner as above described.

In practice various modifications of the inven tion may be made, and any suitable mar 5 terials and proportions may be used without ing the side at the limits of its movement.
